Patented Sept. 23, 194i 2,256,649 STOV Ben M. Rawlings, Chattanooga, Tenn., assigner to Tennessee Stove Works, Chattanooga, Tenn., a corporation of Tennessee Application January 15, 1940, Serial No. 313,938

14 Claims.

My invention relates to improvements in stove doors, and more particularly to a hinging and latching means, whereby a stove door which covers and conceals the oven and s'oot openings of a coal or wood stove can be l'atched and maintained in position when raised to facilitate the easy removal of the contents of the soot chamber.

For the most part, it has been the practice in the prior art to provide the soot chamber with a separate closure which is opened or removed when it is desired to remove the contents therefrom. The practice in the prior art has also been to hingedly mount the door adjacent its lower end on the casing of the stove near the base of the oven, and to provide a panel just beneath the door and behind which is positioned the soot closure or tray, necessitating the removal of the panel each time the soot is to be cleaned out of the stove. This introduces an additional panel in the casing, detracts from the beauty of the stove, increases its cost of manufacture, and destroys the balance of the stove front. These objections are greatly accentuated Where the front of the stove has a surface of porcelain enamel. It is further found to be diflicult to obtain a freely removable mounting for -a lower panel section, and no adequate means can be attached to the panel to facilitate its removal without detracting from the appearance of the stove. Accordingly removal of the panel is rendered very diicult. The use of tools in prying the panel often serves to scar its outer face. In order to properly mount the panel in place additional mounting means must be employed, so that the difficulty in precisely positioning the panel to insure a proper fit is greatly increased.

Applicant with a knowledge of all of these defects in and objections to the prior arthas for an object of his invention the provision of a stove having an oven door with an extension that eliminates the soot closure cover panel without essentially altering the other associated elements and their relation to each other, and without increasing the operating mechanism of the door materially, or reducing the ease of operation.

Applicant has as another object of his invention the provision of a door for an oven which when closed projects down over and covers the soot closure as well as the oven door opening, and when open assumes the position of the open door of the'conventional stove, exposing the soot Closure.

Applicant has as another object of this invention the provision of an oven door of a stove which, in closed position, projects down over the soot closure as well as the opening of the oven,

' and thus eliminates the soot closure panel with all of its supporting structure and reduces the time and cost of manufacture, removes V'the danger in scarring a panel when being removed, yas was formerly the case, and gives a balanced front for the stove, as well as eliminating the necessity for making a panel and a door in two separate pieces, and fitting them into place.

Applicant has as a further object of his invention the provision of a door Alatch for maintaining the lower end of the door from projecting overthe soot closure when such door is in a semi-closed position torfacilitate the removal of the closure and the cleaning of the soot,

Applicant has as a still further object of his invention the provision of an oven door for a stove employing a floating hinge for mounting the door tothe stove intermediate the upper and lower edges of the stove door, whereby the closing of the door causes its lower end to ride down over and conceal the soot closure,r and when opened to ride up and assume the position of an' oven door on a conventional stove.

Other objects and advantages of my invention willpappear in the following specification and accompanying drawings, and the novel features thereof will be particularly pointed out in the annexed claims. In the drawings, Figure 1 is a front elevation of a range embodying one form of my 'present invention. Figure 2 lis a side elevation of the same range showing my improved door in open position.

' Referring to the drawings in detail l designates the top of a range or stove which stove has a front utility compartment door 2 hinged adjacent one edge of said stove for movement upwardly. On the opposite side of the front of the stove, vand hinged in like manner, is a combination ash and fuel door 3. Positioned intermediateof said doors is an oven door 4 which when closed normally covers both the oven opening of the stove, dened in Figure l by broken lines, and the closure 6 for the soot chamber, also indicated by broken lines, thus eliminating the usu-al soot closure' panel now in general use. Near the upper edge of the outer face of the door 4 is mounted the usual handle 5 for openingy Y The door 4 is mounted upon the stove the door.

through the oven and out through the back wall f' thereof. Portions of the :free ends of the rods- 9, 9 project on'beyond the rear 'wall of the stove and have disposed thereabout, between the rear" wall and the end of the rods, helical compression springs III-.Ill which are retained against removalvby crosspins I I which are seated in transverse openingsIZ-IZ.' y However, if desired, these. crosspinsV may be eliminated and the outer ends of the springs may beinserted in said openings. Mounted yon the door at points` below the places where'the ends of rods 9-'9 are pivotally joined to the stove door 4 are rollers 8 8. f

Passing through the stove casing above the VsootV closure 6 are spaced opleningsfI-l for ,the

reception of the Vends I9-I9 of the anchoring element carried by'said door for latching it, when in semi-closed position, at a point above the soot closure tofacilitate the removal of soot from the chamber.

My improved door 4, shown'in Fig. 4 with cover 29 removed comprises 'a front walll having an upturned circumferential ange defining its out--V er extremities. Disposed withinV the flange' I3 and mounted upon the innerfaceof the outer wall are Vspaced pairs of oppositelyfaced angle brackets II-V-II and Il-'I'I adjacent the lower edge Lof' said door.

Mounted on the outer face of the lower end of the channel member 2U is a bearing 28 having a projection which overlaps and is se-V cured adjacent the lower outer face of said channel member 29, the lower end of said bearing being curled to receive the body of a rod or anchoring element having downturned ends I9-I9 which are adapted to pass through appropriate openings in the circumferential ange I3 eX- tendlng along the lower end of the door 4. The operating mechanism for the channel member 29 and associated elements comprises an arm 26 `running longitudinally of such door through the central portion and having an end which Vextends through its'upper ange I3 and which may be curved'to form a finger 21 to facilitate the movement of the arm. Joined to the lower end of arm 26 and disposedl within the flange I3 is a block 2| pivoted intermediate its ends at 23 and adjacent one end to arm 26 at 25 and at the other end to channel member 20 at 22, the lower edgeof. the cover Y29 being slotted to facilitate ready movement of the block 2| which passes' into such cover.V

Positioned over the inner face` of the. door 4 is a cover. plate I4'having a flangefalong itsedge which overlaps the Aflange I3, the ,cover I4`being held in place by appropriate screws.

VThe operation of nthe door is as follows: l

Starting from the closed position Yo" Figure 1 door 4 overhangs the lower edgebf, the oven opening and conceals the soot 'closure .thus re' placing the soot closure panel. As outward force is-A applied tothe handle 5, the top ofthe door moves outwardly'and theY rollers 8.-8move up the. face "of the wall of the stove and pivots I 5-I 5 move downwardly until. the upper face of plate I4 .isv substantially co-extensive with the'bottom Y of 'the' oven at which point ,the rollers 8-8 come i located adjacent the lower end Yof said door 4Vis l a cover plate 29 having a projecting flange along into engagement with grooves inthe lower edge of rods 9- 9 and prevent further upward movement. The door-will then be maintained in horizontal position. 1 j'. The door is closed by imparting an initial force to the handle 5 moving the upper edgeof such-door ,4' towards the top of the opening of the oven, so that the rollers Y8 8 roll, down the face of the front of the'stcve under the'influencefoffsprings ill-' IIJ 4which tend to urge the door `4` Ato closed position. As the door reaches its closed position, the rollers have traversed theV distance representing the distance of the portion ofthe'. front of the stove which is overlapped byV the projectingdoor and the upper edge just overlaps the .top of the -oven opening. Q

'I'he door in open position, it will be noted, Y

has moved up to clear the soot closure 6 andwill permit the removal' of the vsoot therefrom. However, suchY door being in horizontal position will greatlyhamper the operations necessary for soot removal. Accordingly, it is desirable to have the door moved out of horizontal position4 to facilitate access to the closure 6.

In order Vto accomplish this, the door, beingin horizontal position, mustb'erclosed, but before this operationis begun, the finger 21 is manually' pulledA outwardly causing more -of the arm 26-to move out ofthe door and imparting a clockwise movement to the bloclr'ZI about its Divot 23, which in turn impartsadownward movementv tofchannel member20 which carries the rod in. bearing 28 and projects the ends I9-I9 ofthe rod out through the lower edge of the door and into the openings '1 -I of the front wal1of.theV

are prevented Afrom moving downwardly from the anchoring portions l9--I9 and the door assumes a positionindicated in Figure 3 as it is moved upwardly. This exposes the closure member 6, and removes the door 4 from interference with'the soot removing operations. V

When the soot has been removed and the closure reinserted in the stove, the handle is moved downwardly until the door is again in horizontal position, indicated in Figure 2. The linger 2'? is then pushed inwardly moving arm 2e downwardly and swinging block 2| about its pivot 23 thus raising channel member 20 with its bearing 28 and rod and removes the ends of such rod I9-l9 from the openings 1-1 thus releasing the door so that it may be closed in the manner hereinbefore described.
